    摘要:

    【摘要】 随着我国人口老龄化趋势加剧,腹主动脉瘤发病率逐渐升高。由于动脉瘤破裂后死亡率极高,该病已经成为危害我国人群健康的重要疾病之一。在组织病理学上,腹主动脉瘤表现为中膜平滑肌细胞耗竭、弹力纤维断裂和退化、细胞外基质降解和血管局部炎症反应等。目前,临床上腹主动脉瘤的治疗多以血管内介入治疗为主,缺乏药物治疗手段,这也与该病致病机制迄今仍未被完全阐明有关。目前腹主动脉瘤动物模型主要以啮齿类实验动物模型(小鼠和大鼠)为主,也有部分中、大型实验动物模型(如兔、豚鼠、犬和猪等)。在造模方法上,主要包含弹性蛋白酶动脉腔内灌注法、血管紧张素II输注法、氯化钙涂抹法和血管组织移植法等。部分药物或手术腹主动脉瘤模型由于前期诱导刺激的停止,诱导后动脉瘤趋于稳定。开发允许腹主动脉瘤持续发展,甚至可以在人为刺激下诱导破裂的,更符合人动脉瘤发展规律的模型是今后的造模研究方向之一。实验动物模型在阐明腹主动脉瘤发病机制、开发治疗动脉瘤新药和评价相关治疗策略安全性的重要研究工具。因此,本文综述了目前常用的腹主动脉瘤造模方法和其在临床前转化研究中的应用。

    Abstract:

    With the population aging in our country, the incidence of abdominal aortic aneurysm(AAA), an aged disease, has gradually increased. Because of the high mortality of ruptured AAA, which became one of the most severe life-threaten diseases. In histopathology, main AAA pathological features include elastin degradation, smooth muscle cells (SMCs) depletion, extracellular matrix digestion, and mural leukocytes accumulation. In clinics, open/endovascular repair remains the effective strategy for AAA management, and the drug therapy is still lacking. The detailed molecular mechanism of AAA is still unclear, which is one of the important bottlenecks affecting the development of potential drug targets. Animal models are the most powerful tools to clarify the pathogenesis of AAA. Though some medium to large laboratory animal models (such as rabbits, guinea pigs, dogs and pigs) are established for AAA study, rodent models (mice and rats) still take the first place in this field. At present, the methods to induce AAA include intra-infrarenal aortic infusion of elastase, subcutaneous infusion of angiotensin II (Ang II), periaortic calcium chloride painting, decellularized aortic xenograft and so on. For the cease of pre-induced stimulation (medical or surgical), AAA tends to stabilize in most models. Therefore, the development of ideal animal models, which maintains the continuous aortic dilation and even rupture, remains a problem. AAA animal models are helpful in elucidating the pathogenesis, screening new drug targets and promoting its clinical translation. This review aims to discuss the application of current AAA modeling methods and their translational relevance.
